• analytical chemistry is the branch of chemistry involved with the analysis of chemical substances
• analytical chemistry is the characterization of matter
• analytical chemistry is also called as measurement science
• analytical chemistry involves separating, identifying, determining
• separating are separation techniques such as reduction of samples, filtration, and extraction
• identifying are qualitative chemical tests
• determining are the relative amounts of the components of the sample
• qualitative analysis involves the identification of substances of interest
• quantitative analysis id the determination of concentration or amount of substance present in a given sample
• analyte are the components of a sample that are to be determined
• qualitative analysis deals with the identification of elements, ions, and compounds in a sample
• quantitative analysis deals with the determination of how much of one or more constituent is present within a sample
• qualitative analysis tells what is in a sample
• qualitative analysis is the identification of elements and measure changes in color, mp, bp, odor, reactivity
• quantitative analysis tells "how much" is in a sample, and is expressed in concentration where numerical data are collected
• the two kinds of quantitative analysis are classical chemical analysis and instrumental analysis
